Converting from IEnumerable to List [duplicate]
...o this very simply using LINQ.
Make sure this using is at the top of your C# file:
using System.Linq;
Then use the ToList extension method.
Example:
IEnumerable<int> enumerable = Enumerable.Range(1, 300);
List<int> asList = enumerable.ToList();

Linq Query keeps throwing “Unable to create a constant value of type System.Object…”, Why?
...this is in the context of an IQueryable, so it's not compiled into regular C# code. It becomes an expression that is passed to a query provider. That query provider can do whatever wants with the query, and it may handle Equals and == the same or not.

Mod of negative number is melting my brain
...
Please note that C# and C++'s % operator is actually NOT a modulo, it's remainder. The formula for modulo that you want, in your case, is:
float nfmod(float a,float b)
{
return a - b * floor(a / b);
}

Setting a WebRequest's body data
...nother one. Most likely you have been given an api and want that into your c# project.
Using Postman, you can setup and test the api call there and once it runs properly, you can simply click 'Code' and the request that you have been working on, is written to a c# snippet. like this:
var client = n...
How to use LINQ to select object with minimum or maximum property value
...
So you are asking for ArgMin or ArgMax. C# doesn't have a built-in API for those.
I've been looking for a clean and efficient (O(n) in time) way to do this. And I think I found one:
The general form of this pattern is:
var min = data.Select(x => (key(x), x)).Min...
How to convert byte array to string [duplicate]
... This only works if your string was encoded with UTF16 which is c# string's default internal encoding scheme. If, say, the byte array was encoded simply with ASCII chars from the original string (assuming it can be), after the BlockCopy, each char will be squeezed with two such ASCII char...
Why does ReSharper tell me “implicitly captured closure”?
...l memory leak, and that is the reason for the R# warning.
@splintor
As in C# the anonymous methods are always stored in one class per method there are two ways to avoid this:
Use an instance method instead of an anonymous one.
Split the creation of the lambda expressions into two methods.

Unit test naming best practices [closed]

var bankAccount = new BankAccount();
bankAccount.Deposit(100);
